TV VIEWERS in the central Borders will be required to retune their sets at the start of next month.

Some Freeview channels are moving to new airwaves to allow for the development of new mobile broadband services.

Around 18,000 homes served by the Selkirk transmitter will be affected.

Changes at the transmitter will be completed this (Wednesday) morning by around 9:30am.

After this, any viewers receiving their TV signal from Selkirk who find they are missing BBC channels should retune to get them back.

High-definition BBC channels will not be affected.

Retuning will need to take place from March 1.

John Craske from Freeview said: "Following a decision by Ofcom, the media regulator, transmitters across the UK are being updated region by region as part of a major engineering programme being carried out between now and 2020.

"Retuning should be straightforward and some TV equipment will retune automatically.

"Anyone who needs advice, or who finds they are still missing BBC services after retuning, can visit the Freeview website at www.freeview.co.uk/borders or contact the Freeview Advice Line for free on 0808 100 0288."

Some older aerials may need to be replaced to continue receiving the channels which have changed.
